.To all whopt it may concern:

Be it known that I, Fnr'imiinro PITTARD, a citizen of Switzerland, residing at 90 Boulevard du Nord, Lyon, France, have invented new'and useful Improvements in Readers or Machines for Perforating Paper to be Used with the J acquards in Automatic Embroidr ery- Machines, of which the following is a specification.

The invention consists of a machine for perforating the paper used in the working of the jacquard in the automatic embroiderymachine forming the subject of United States Patent No. 714,129, dated November 25, 1902. In this machine the fabric is stretched on a vertical frame, which is moved These movements are 4 obtained simultaneously in the vertical and the horizontal direction by series of pawls acting on racks or ratchets arranged in steps. The jacquard chooses from. each series the pawl suitable for the motion to be given, this choice being determined by the holes perforated in the paperpassing through the jacquard. The automatic reading has for its object to perforate these holes in the paper according to the indications given by the design to be reproduced, these indications be- .ing first transmitted to cylinders, which are perforated-according to a similar arrangement to that of the racks or ratchets in steps employed in the embroidery-machine, and these cylinders then transmit them to the erforator. The accompanying drawings llustrate the arrangements employed for this purpose.

Figure 1 is a general view of the apparatus. Fi 2 is a development of the perforated cylin ers. Fig. 3 is a transverse section of the perforator. Fig. 4 is a, longitudinal section of the same drawn on the line A A of Fig. 3. 5 is a front view of the same, showing the drivin mechanism. Figs. 6 and 7 are'de tails 0 Fig. 3.

The apparatus shown in Fig. 1 consists of two parts-the reading apparatus, which follows the contours of the design drawn on a very large scale on the vertical board b, and the erforator, properly so called.

In out of the board I) moves vertically a horizontal rod (1, guided .by the u rights f, and on the rod (1 moves horizonta ly acarriage g, carrying a pointed finger h, which can thus be caused to follow all the contour of the design drawn on the board I). The

rod (1 is supported by two metallic ribbons 1" 7 passing) over pulleys 2 2 and uniting into a single rib on j, which descends from the pulley 3 to operate the cylindena'ofthe perforator, rises over the pulley 4, andis termi 6c nated by a counterweight k; balancing the weight of the rod d, which can thus be moved without much effort. To the carriage g are attached the two ends of a metallic ribbon l,

which passes round the pulleys 5 5, mounted at the ends of the rod (1, rises and passes-over the, pulleys 6 7, is stretched by a counterweight m between the pulleys 7 and 8, descends from the latter to drive the c linder c of the perforator, and returns over t 1e pulley 7o 9 to the pulley 6. The counterweightm en ables the ribbon Z to remain always stretched notwithstanding the vertical motion of the rod 11. It results from these arrangements that the vertical ascending or descending 7 5 movements of the carriage g are transmitte j,- to the" cylinder 0 in extent and direction that its horizontal movements to right or left are transmitted in the same manner to the cylinder 0 and that it is only necessary'to bring the finger h to any point of the board I) to bring by that means the cylinders a and :0 to a determined position corresponding entirely to this point. In order to insure this agreement, the pulleys 33,'Figs. 1, 3, and'4, round which pass the ribbons and Z, are furnished with teeth which gear with perforations o the ribbons.

Independently of the operation of the cylinders a and c, which serves to read the de- .90

sign, the reading apparatusalso comprises the operation of various parts serving for putting the perforator in operation and to the piercing of holes which, in the embroidery-machine, act to determine accessory func- 5 tions, such as the stoppage of the machine, the tension of the threads, &c. v This operation is effected by hand at the moment convenient to the reading and by means of rods,

such as n 0, of variable number, extending the zoo entire length of the rod (1- and capable'of being operated at the same time as the carria e 9. These rods n 0 carry at one of their en 3 fingers e i, which bear upon verticallystretche'd metallic ribbons p These rib- 1.05 bons p q thus shortened by the pressure of the 1 I i F3 ,7 A bent in the form or rubs can enter the perversinesns of the cam 11. and levers 11-3.

The pcrlorstor, Figs. 3, "-5, and 5, consists, first, oi two cylinders a and the surface which is perforated, izidicetcd by the dcvclopincto 1', Fig. 2, and upon. which hem se ries :2? iii ers 20, the ends of which be tions; second, of inecl'isnism for drawing paper forward; and, third, of the pernireting mechanism. The paper 11:, supplied from an 1 exterior roller, passes through the perforate!

Ordinarily. the pin 24 is disengaged from the notched Wheel and engaged in a fixed notch carried by the arm 27. lit 1n :iintained in this position by a pawl .23, con nected to the ribbon u.

These are then fixed to their exact po- SltiOIl when. the fingers 2i), .i igs. 3 and t, liberated from the raising-levers 18, come to bear upon their surface. (em 1. 9 is secured on shaft 10, which makes but one revolution during each o perotion.

given position of the cylinder 4L single finger or" each series can enter the per'loret'ions.

These [lo ers then push back in the perforch 'iugr apparatus o the rods 34-, the heads of which become placed above corresponding punches, so. that when the perforating*appnretus is operated by the levers 12; these punches alone pass through the paper: "Other punches operated at each stroke perl'oritte on the edges the holes, serving to draw the pa per fOPWHtl. either by theroller 12 or by the jacquard. liostly, other fingers 35 (shlmn in (.letzril at Fig. 6) can :it the will of the reader operatespecial punches of variable nmiober. (These lingers, raised like the others by the rcising-lcvers 18, are placed in action by the ribl'mns i t, which. operate the cylinders 36, furnished with a groove which comesin front of the nib oi the finger when the reader open ates the correspondin; ribbon i. The holes perforated by these punches serve to deter-- mine accessory functions ol' the embroiderymachine and nmy be varied in number end position, according to the nature of the embroidery to be executed. Each point of the design is thus figured on the paper by two rows of holes, one of which corresponds to reron'nnencc the vertical position of the point and the other to its horizontal position. These two rows of holes transported into the jacquard and placed in relation with two series of pawls of a similar arrangement to that of the lingers of the perforator will place in operative position certain of these pawls, which acting the ones on the horizontal motion, the others on the vertical motion, of the fabric will bring before the embroidery-needle the point corresponding with the point l'igured on the design.
